Abstract

A soft light-guide member is provided. The soft light-guide member is adapted to guide a light beam provided by a light source. The soft light-guide member includes a light-entering portion and a light-emitting portion. The light-entering portion corresponds to the light source. The light beam enters the soft light-guide member via the light-entering portion, and leaves the soft light-guide member via the light-emitting portion. The soft light-guide member includes transparent silicone rubber. A diffusion microstructure is formed on the surface of the light-emitting portion.
